A 69 trans am with 303 is completely un true . A special 303 5.0 liter engine was designed for SCCA gr II sedan racing ,that was not available in any production car in any time .
All of this is a fiction . 250 unit ???????

Same deal like GTO Ram Air V. But this Firebird got smaller engine. A race programmed 303 Cu Ram Air V. Redline is still same: 8000 rpm like GTO Ram Air V. It's very rare and the Ram Air V part it's not readily available. It estimated Pontiac only built less than 250 unit
